Enum Constant Detail

NEW

public static final SequenceState NEW

Initial state of a sequence. Source: From construction till CreateSequence is sent Destination: Not used, transition directly to CREATING

CREATING

public static final SequenceState CREATING

Sequence creation handshaking is in progress. Source: From CreateSequence send till CreateSequenceResponse is fully processed. Destination: During processing of CreateSequence till CreateSequenceResponse is sent.

CREATED

public static final SequenceState CREATED

Sequence handshaking is complete. Processing sequence messages. Source: After processing CreateSequenceResponse until either a LastMessage is sent, sequence is closed, or sequence is terminated. Destination: After CreateSequenceResponse is sent till the sequence receives LastMessage, CloseSequence, TerminateSequence or the sequence times out. Timeout will cause the sequence to be forcibly terminated (in RM 1.1 and beyond this will send TerminateSequence to the RM source).

LAST_MESSAGE_PENDING

public static final SequenceState LAST_MESSAGE_PENDING

Deprecated.

RM 1.0 only

RM 1.0 Only. Source: Indicates a LastMessage has been sent. Destination: Indicates a LastMessage has been received and is being processed.

LAST_MESSAGE

public static final SequenceState LAST_MESSAGE

Deprecated.

RM 1.0 only

RM 1.0 Only. Source: Indicates a LastMessage has been sent and ack'd. Destination: Indicates a LastMessage has been received and ack'd.

CLOSING

public static final SequenceState CLOSING

Sequence is in the process of being closed. No sequence messages can be sent or received. Source: Upon send of CloseSequence until CloseSequenceResponse is processed. Destination: Upon receipt of CloseSequence until CloseSequenceResponse is sent.

CLOSED

public static final SequenceState CLOSED

Sequence is closed. No sequence messages can be sent or received. Source: After CloseSequenceResponse is processed. Destination: After CloseSequenceResponse is sent.

TERMINATING

public static final SequenceState TERMINATING

Sequence is in the process of being terminated. No sequence messages can be sent or received. Source: After sending TerminateSequence till TerminateSequenceResponse is processed. Destination: After TerminateSequence is received until TerminateSequenceResponse is sent. Timeout will cause the sequence to be forcibly terminated (in RM 1.1 and beyond this will send TerminateSequence to the RM source). Sequence moves immediately to TERMINATED.

TERMINATED

public static final SequenceState TERMINATED

Sequence is terminated. No sequence messages can be sent or received. Source: After TerminateSequenceResponse is processed. Destination: After TerminateSequenceResponse is sent. Timeout will cause the sequence to be forcibly terminated (in RM 1.1 and beyond this will send TerminateSequence to the RM source). Sequence moves immediately to TERMINATED.
